我一直在尝试执行一个程序来对数组中的变量进行排序，但我一直得到一个';' 程序应该从函数中检索数组的数组声明后的行中的预期错误。任何帮助，将不胜感激。

This is bad syntax (which causes the ';' expected error ):

oddNumbers[] = getOddNumbers(randomNumbers);

The brackets are not needed. You can do this:

oddNumbers = getOddNumbers(randomNumbers);

Besides that, you have plenty of errors:

int randomNumbers[] = new int[100]; // you need the brackets

Your return value in the method declaration is wrong (you are returning an array, not an int):

public static int[] getEvenNumbers(int randomNumbers)

   int oddNumbers[] = new int[100];

通过初始化oddNumbers成为一个数组。当您要分配值时，

    oddNumbers={elements of array}

左右两边都应该是数组。

也许您应该使用 IDE 进行编码，那么它可能会帮助您理解一些这样的问题。
